[en] In August 1973, the Agency concluded a market survey of nuclear power in fourteen selected developing countries throughout the world. The results of this survey have been reported in individual country reports and in a general report. A summary report on the survey was presented at the seventeenth regular session of the Agency's General Conference. These results indicated that in the fourteen countries surveyed, about 60,000 MWe of nuclear plant capacity might be put into operation during the 1980 to 1989 period. About 94 % of this capacity was represented by units of 600 MWe or larger since under the economic conditions which prevailed in early 1973 nuclear units in the 200 - 400 MWe size range were generally found to be uneconomical compared to oil-fired plants. Following completion of the Market Survey, a very preliminary evaluation of the total potential nuclear market in all developing countries of the world was carried out by Agency staff using the Market Survey results as a basis. This extended study which was completed in late 1973 indicated that the total capacity of nuclear plants which might be installed in the developing world during the 1980 to 1989 period could amount to approximately 160,000 MWe. Of this amount the capacity of small and medium power reactors (200 - 400 MWe) was less than 10,000 MW

[en] Underground coal gasification (UCG) is a process conceived over a hundred years ago and used successfully, since the 1940s, to generate low-Btu gas for electric power production. The process is applicable to many coal resources that cannot, for a variety of reasons, be economically produced. While UCG cannot compete economically with conventional oil gas, and coal reserves, emerging nations requiring electric power for development of an industrial infrastructure may provide the niche market that is necessary for the commercial development of UCG. Recent UCG field testing, conducted in the United States, demonstrated that UCG could be successfully conducted without adverse environmental impact. This testing also resulted in increased understanding of the interactions between the UCG process and the local hydrogeological environment. With this knowledge, the probability of successful commercial UCG development can be increased by selecting a UCG site with hydrogeologically and economically favorable properties. And approach for commercial UCG development for producing electric power in emerging nations is presented

[en] This paper presents an up-dated overview to the sixteen photovoltaic pilot plants sponsored by the Commission of the European Communities, with special reference to the problems encountered and lessons learned. Details are given of the Commission's plans for tackling these problems and improving the plants in the lights of experience. (author)

[en] The aim of this report is to describe the present situation regarding biomass utilization in small power plants, 0.5 - 20 MW fuel power. Also discussed are the most important technical, economical and environmental conditions which may prevent a fast expansion of small biomass fueled power plants for generation of district heating in smaller networks and also for electric power generation. Biofuels means a reduction of the net emission of carbon dioxide, but emission of other compounds are not very well known for this size of power plants. There are only a few biofueled power plants in Sweden and only a couple with less than 20 MW power supplied. New concepts are under development but not much have been achieved during the most recent years. 25 refs, 10 figs, 9 tabs

[en] The paper presents an example of capacity value (kW-value) evaluation of photovoltaic generation from power companies generation planning point of view. The method actually applied to evaluate the supplying capability of conventional generation plants is briefly described. 21 figs, 1 tab

[en] The paper addresses the link of fusion and fission safety and two surveys performed in France on samples of similar size and composition before and after the Chernobyl nuclear accident (February 1986 and June 1986 respectively). Comparison of the results obtained indicate on which aspects of nuclear power safety the public is most sensitive. (author). 3 refs, 1 tab

[en] The actual and projected electric power station building programs of several countries and regions have been examined to determine what effect the introduction of nuclear power has on fossil fuel usage by the electricity system. It was found that (1) nuclear power leads directly to savings in fossil fuel usage, a larger nuclear component leading to larger savings; (2) individual nuclear stations rapidly wipe out the energy 'debt' incurred during building; and (3) the relatively short periods of consolidation in the early stages of a nation's building program usually prevent the nuclear component from going into energy 'debt'. Assessments of the energy requirements to build and run various types of power station have been made from the available literature
